so I'm sort of new to blender. I've recently started to experiment with nodes and render layers. Currently, I'm trying to make one object (and the shadows cast by it) blurred. I've tried running the object through a blur filter node, but that doesn't appear to have done anything with the shadow on the other object (which is sort of cool because I can use it for focus and perspective trick, but isn't so convenient for me.)

How can I get both the object and it's shadows in other render layers to both be affected by this node?

Fake way to do it is increase the size of the light, a lot.

fake: big light

Another fake way to do it is by mixing a transparent node with your shader and use facing layer weight for factor

fake2: transparent surface shader

(sorry for self hosting, imgur declined my request)

And now the real way: volumetrics

Real: volumetrics

Plug a volume scatter shader to the volume output and control it's density with a spherical gradient. Probably can be modified for non spherical objects too.
